THE WS-TPLLO and WS-TVPLLO light level detectors from Amalgamated Instrument Co (AIC) are compact IP65 rated transmitters with a 4-20mA or 0-10V dc output that varies with the incident light.
The IP65 rating makes the sensors suitable for outside applications but they can also be used for interior applications.
Highlights of the sensor include:
* 4 ranges: 0-2500 lux, 0-5000 lux, 0-10,000 lux and 0-20,000 lux.
* 4-20mA or 0-10V dc output
* 0-10V dc output model can be powered by 24V ac or 24V dc. The 4-20mA model is powered by 24V dc.
* Operating temperature -50°C to +50°C.
This sensor would be useful as part of a comprehensive environmental monitoring system that could include temperature, humidity, wind speed and wind direction.
Other applications could include shade control for greenhouses, for hydroponics, for light level control in livestock sheds, poultry farms, etc, or for ambient lighting measurement in large populated areas such as convention centres or shopping malls.
